Description

Technical Field

[0001] The utility model relates to the technical field of waste rubber processing, in particular to a waste rubber processing device. Background Art

[0002] Waste rubber refers to discarded rubber products, mainly from scrapped tires, rickshaw tires, hoses, tapes, industrial sundries, etc., as well as scraps and waste generated during the production process of rubber product factories. If these wastes are not properly treated, they will pollute the environment. The waste rubber processing device can process the waste rubber by crushing or desulfurizing, etc., so that the waste rubber products can be converted into reusable raw materials or energy.

[0003] After searching, the Chinese patent application number 202021227840.9 discloses an environmentally friendly recycling device for waste rubber, including a device body and a feeding port, the feeding port is fixedly connected to the top of the device body, the outer side of the device body is fixedly connected to a support frame, the inner side of the support frame is fixedly connected to an air pump, a heating nozzle is arranged below the feeding port, the lower part of the heating nozzle is fixedly connected to a support platform, the inner end of the support platform is fixedly connected to an extrusion roller, and the interior of the support platform is fixedly connected to a first motor. The operation of the first motor drives the relatively arranged extrusion roller to rotate, thereby extruding the rubber, and the operation of the electric telescopic motor drives the cutting mounting plate to move back and forth horizontally, driving the cutter at the front end position to cut the rubber in a vertical state, and when the cutter is cutting, the rubber in a vertical state is pressed against the horizontal opening on the surface of the supporting side plate, thereby facilitating cutting;

[0004] However, the existing processing device still has the following shortcomings during use: since the waste rubber crushed by the existing crushing roller generally falls directly out from the bottom of the crushing box, it is impossible to control the size of the waste rubber crushed, which will cause larger waste rubber pieces to be discharged directly from the crushing box after crushing, requiring staff to manually sort them out, increasing the manual workload of the staff.

[0005] Therefore, a waste rubber processing device is urgently needed to solve the above problems. Utility Model Content

[0006] The utility model aims to solve the problem that the discharge of waste rubber of different sizes cannot be flexibly controlled at present, so that larger unqualified waste rubber pieces after crushing are mixed with qualified ones and directly discharged from the crushing box, and the staff need to manually sort them out, which increases the manual workload of the staff and affects the crushing efficiency.

[0007] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0008] A waste rubber processing device comprises a base, both sides of the top of the base are connected to support frames, and a screening structure is arranged on the inner side of the support frame, a crushing box is connected to the top of one side of the support frame, and a first support platform is fixedly connected to one side of the crushing box, a second support platform is fixedly connected to one side of the crushing box, a first motor is installed on the top of the first support platform, a second motor is installed on the top of the second support platform, a rotating shaft of the first motor is connected to one end of a first crushing roller through a bearing, a rotating shaft of the second motor is connected to one end of a second crushing roller through a bearing, a feed port is fixedly connected to the top of the crushing box, and a material control structure is arranged at the bottom of the crushing box.

[0009] As a preferred technical solution of the present application, the material control structure includes a second top rod fixedly connected to one side of the top of the screening box, a first top rod fixedly connected to the other side of the top of the screening box, a first baffle hinged to one side of the bottom of the crushing box, and a second baffle hinged to the other side of the bottom of the crushing box.

[0010] As a preferred technical solution of the present application, the fork bars on the first baffle plate and the second baffle plate are staggered, and the tops of the first push rod and the second push rod are in contact with the bottoms of the first baffle plate and the second baffle plate respectively.

[0011] As a preferred technical solution of the present application, the screening structure includes a buffer spring arranged on a support frame, a screening box connected to the top of the buffer spring, a screening mesh fixed on the inner wall of the screening box, a first discharge port connected and fixed to the bottom of the screening box, a second discharge port fixedly connected to one side of the screening box, and a vibration motor installed and fixed to the bottom of the screening box.

[0012] As a preferred technical solution of the present application, the buffer springs are symmetrically distributed at the bottom of both sides of the screening box, and the screening net in the screening box and the outlet of the crushing box are located on the same vertical line.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the scheme of this application:

[0015] 1. The size of the waste rubber crushed and discharged from the crushing box can be controlled by setting a material control structure. The second push rod and the first push rod are gradually raised or lowered with the large-scale vibration of the screening box, and the staggered first baffle and the second baffle are lifted or lowered accordingly, and then the small pieces of waste rubber after crushing can be discharged from the gap separated by the first baffle and the second baffle, and then the larger waste rubber is retained and gradually lifted up by the gradually rising first baffle and the second baffle to contact the rotating first crushing roller and the second crushing roller again for secondary crushing, until it can be discharged from the gap between the first baffle and the second baffle and stops, thereby achieving the effect of controlling the size of the waste rubber discharged;

[0016] 2. The size of the discharged waste rubber is further refined and screened by setting a screening structure. The vibration motor is started to drive the screening box to vibrate through the buffer spring. Then the screening net screens the crushed waste rubber discharged from the crushing box as the screening box vibrates, so that the qualified waste rubber passes through the pores of the screening net and falls into the bottom of the screening box and is discharged from the first discharge port. At the same time, the unqualified waste rubber left on the surface of the screening net is discharged into the collection box on one side through the second discharge port for collection, so as to be poured back into the device for secondary crushing.
